Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If panoramic video stream is uploaded to server for processing, then video transmission can be achieved, but end-to-end delay increases and downlink data volume increases
Solution Approach 1:
The patent introduces mobile edge computing nodes as intermediaries between the shooting device and terminal devices. These edge nodes perform video processing locally at the network edge, acting as a mediator that reduces the need for centralized server processing and minimizes data forwarding through the core network, thereby reducing end-to-end delay and simplifying routing.
Solution Approach 2:
The patent segments the video processing function from the centralized server architecture and distributes it to multiple mobile edge computing nodes. This segmentation allows processing to occur closer to the data source and consumers, reducing the need for complete video stream forwarding to a central server and back, thus reducing delay and simplifying the overall routing process.
2Manufacturing precision
If high-resolution panoramic video is transmitted, then video quality is improved, but bandwidth consumption and data volume increase significantly
Solution Approach 1:
The patent extracts and transmits only the relevant portion of the panoramic video stream based on the terminal device's pose information. Instead of transmitting the complete high-resolution panoramic video, the system identifies and transmits only the specific region of interest corresponding to the user's field of view, significantly reducing data volume while maintaining video quality for the relevant area.
Solution Approach 2:
The patent applies local quality processing by generating a video stream that focuses on the specific region of interest for each terminal device based on its pose. The video processing adapts the quality and content locally according to the user's viewing direction, ensuring high quality where needed while reducing overall data transmission requirements compared to transmitting the complete panoramic stream.
3Adaptability or versatility
If complete panoramic video stream is processed, then all viewing angles are covered, but processing load and bandwidth requirements increase
Solution Approach 1:
The patent implements dynamic video stream generation that adapts to the terminal device's real-time pose information. The processing is dynamically adjusted based on the user's current viewing direction, generating only the necessary portion of the panoramic video for the current field of view. This dynamic approach maintains adaptability to different viewing angles while significantly reducing computational load compared to processing the complete panoramic stream.
Solution Approach 2:
The patent applies partial action by processing and transmitting only the necessary portion of the panoramic video stream corresponding to the terminal device's field of view. Instead of processing the complete 360-degree panoramic video, the system performs partial processing on the relevant region, reducing computational load and bandwidth requirements while still providing complete coverage for the user's current viewing angle.
